How do people get crab lice?

People typically get crab lice, or pubic lice, through close physical contact with an infested person, most commonly during sexual activity. The lice can also be transmitted through sharing infested clothing, bedding, or towels. Although they are commonly associated with the pubic area, crab lice can also inhabit hair in other parts of the body. Good hygiene and avoiding close contact with infested individuals can help prevent transmission.
